The Lennox 14D97 Hydrolevel HydroStat Control (OEM part number 240009113) is a factory-approved boiler control designed for use on Lennox GWB8 series gas boilers, covering models from GWB8-050E through GWB8-299E. This control serves as the primary operating and safety module, combining temperature regulation with integrated low-water protection to ensure reliable and safe boiler operation.

The HydroStat control continuously monitors boiler water temperature and water presence through its integrated sensor. By preventing burner operation under unsafe low-water conditions, it helps protect the heat exchanger from damage while maintaining efficient heating performance. This control is engineered to Lennox OEM specifications, making it a direct replacement for failed or aging controls in compatible GWB8 boilers.

Designed for residential and light commercial hydronic heating systems, the Lennox 14D97 Hydrolevel control delivers dependable performance, improved system safety, and long-term reliability when installed by a qualified HVAC professional.
